This is the web site of Denis Defreyne, a software engineer living in Berlin.
I am a software engineer with extensive experience in backend and frontend development, and comfortable with infrastructure, security, and reliability. I’m good at technical writing, and have a sense of visual design and UX.
I am committed to creating an inclusive culture that’s built on communication and collaboration, and where people can learn and grow.
I use technology only as a means to an end, and what I build will put the user’s needs first, taking into account usability and accessibility.
Built a privacy-first contact-sharing solution for Berlin clubs
Expanded the broadcasting solution for VIMN subsidiaries such as MTV, Comedy Central and Nickelodeon for divisions in Europe and Southeast Asia
Dissertation: Design of a recommendation system for offering services on social-network sites
I have mentored a diverse group of people, as part of CoderDojo, RailsGirls, and SoundCloud’s internship programs.
I regularly give talks, of which Code as data (2018), How to memoize (2018), and Let’s write a parser! (2016) are my personal favorites. For a comprehensive list, see my talks page.
